A “social dilemma” or “social trap” in game theory between two subjects that presents one subject with the choice to act nobly or selfishly whereby their choice to act one way or the other in conjunction with the level of nobility demonstrated by their counterpart leads to respective payoffs (gains or losses) for both sides. This asocial game was initially written as an episode between two prisoners hence the name. (Howard Raiffa, The Art and Science of Negotiation [Harvard University Press, 1982], 346-47)
